Atomic Structure Questions

In an atom, an electron is moving with a speed of $600\text{m/s}$ with an accuracy of $0.005\%$. Certainty with which the position of the electron can be located is ($h=6.6\times 10^{-34}{\text{kg m}}^2{\text{s}}^{-1}$, mass of electron $m_e=9.1\times 10^{-31}\text{kg}$):

Calculate the wavelength (in nanometer) associated with a proton moving at $1.0\times 10^3\text{m/s}$. (Mass of proton $=1.67\times 10^{-27}\text{kg}$ and $h=6.63\times 10^{-34}\text{J s}$):
